Hello! It's very difficult to translate a text which needs a lot of local costums and faith context, maybe that's the reason why you had not received an answer before. Just thinking in English Writing and leaving out any religion concerns, I'll try to make my best effort on your request. This is my suggestion:
Today we celebrate the Bengali New Year. We in Bengal celebrate it with a traditional festival. We hope to begin a new blessing life , leaving missery behind. Bengali calendar was first introduced by the shahanka '8th century king of Bengal' and later it was modified by the Mughal Emperor Akbar with the sole intention to collect taxes. Bengali New Year has been one the main celebrations in rural towns, over the time, Halkhata included singing and reciting along the country, however, this year the perspective of the festival looks very different since the world is struggling against deadly Virus named Covid -19. We all fervently hope that the New Bengali Year brings health and welfare to humanity, and it also erradicates all sinister from the world.
Hope it works!
Warm regards.
